Twenty-eight profoundly deaf students, aged eight to 11, did not recall spatial order of viewed pictures better than temporal order, were not less competent in probed recognition than 66 age-equivalent hearing students, and made fewer recognitions in temporal-probe than in spatial-probe conditions. Other results were found. (Author/MC)

Three experiments were conducted to investigate two key assumptions of the conjoint retention (CR) hypothesis. The primary intent was to determine whether the structural information conveyed by maps or the mimeticism of map icons was critical in facilitating the recall of text. A secondary goal was to explore the involvement of the visuospatial…

When reference cues are added to a pattern copying task, males' performance improves, but females' remains the same. This superior cue utilization may partially explain differences in spatial abilities. The present research attempts to determine the optimum locus for facilitation of copying by reference cues. (RH)

Plomin and Foch's conclusion that sex differences in cognition account for very little of the total variability in test scores is challenged by demonstrating that on a complex test of spatial visualization the difference between males and females accounts for a quite substantial portion of variability.

Twelve blind students (12 to 24 years old) explored haptically the spatial relations among objects on a table top and were then asked to walk all the paths connecting the objects in a large scale environment. The students deduced the overall arrangement of locations from any point in the large scale environment fairly accurately. (CL)

A total of 120 children between four to eight years of age were administered four sets of visual perspective-taking tasks. Results supported the hypothesis that children's task competence would be a fraction of the number and type of spatial relationships embedded in the stimulus displays. (Author/MP)

Initial research is reported on development of a tangible graphics (a display with raised symbols for reading by hand rather than by eye) system and its evaluation by 20 blind adults. Results suggested that tangible graphs are a viable source of spatial information for blind readers. (Author/MC)

To assess the influence of activity on the construction of spatial representations, first- and sixth-graders were assigned to each of three conditions. The child either walked through the environment, performed isolated tasks at four of the environments, or performed interdependent tasks at four of the locations. (Author/MP)

Children considered preoperational on multiple classification skills and left-right conceptions were trained to work on classification problems under different conditions, including two variations of children working in pairs, and a situation in which children worked alone. Those in collective conditions progressed more significantly than those in…

Two cognitive tasks (construction of space and recognition of space) were developed to test the emergence of three spatial concepts ("in", "on", and "under"). Subjects were 60 Israeli children between 18 and 30 months of age. Scalogram analysis and analysis of variance confirmed that "in" concepts developed…

Scales for object permanence and spatial relationships were administered to 98 severely and profoundly mentally retarded children (mean age 13 years) on three occasions, 6 months apart. Differences in the difficulty of the items were quite stable, but their order of difficulty differed appreciably from that for nonretarded infants. (Author/SB)

Eight men and eight women responded "same" or "different" to pairs of geometric figures. Male subjects showed a left visual-field advantage regardless of the level of processing, whereas female subjects did not show a clear-cut hemispheric asymmetry. Results are discussed in terms of sex differences in processing strategies. (Author/SJL)
